Relative Positions Within Stream Transects

Summary

Abstract: 

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor glacial meltwater stream attributes of the region. Optical topographic surveys were performed to produce a layout of the area studied. This file provides a list of distances and height differences for features along the transect line at each site ("T-points"). All heights are relative to the assumed zero value at the transect RM #1. Distances are horizontal.
